I had to send these back. They run small. I need a 10.5 and they don't come in that size. Also the lower part of the boot (foot area) looks cheap. My son commented that I had a nice boot sewn onto a Croc. I have to say they felt very warm and certainly water/ snow proof but I didn't get to test them out. They are also lighter than I expected, which would make longer walks around town more comfortable.

I've been wearing Asics 2100 series and Kayanos for 10 years and have worn no other brand of running shoes. I had the Kayano 18s and LOVED them - bought 3 pairs. I made the mistake of wearing the 19s right out of the box as I have always done with all of my Asics. These run slightly higher above the heel - I got blisters for the first time ever. Also, the toe box is noticeably wider than the 18s - my feet swim in these (width not length). I feel like the arch support in the 19s is not as good as the 18s but it's probably because these are too wide for me. Of course, I wore this pair outside for several hours so can't send them back now. I will try the Kayanos in narrow I guess, but if that fails, I guess I'll have to look for another running shoe...so bummed. Not sure why Asics changed the 19s...please please go back to the 18s at least in width and heel area.

Width and toe box in 20s compared to 18s or 19s?

I've worn Kayanos for quite a while - always a 10.5 Medium width...loved the 18s but the width and toe box of the 19s were wider than I was used to. Can someone who wears this model year after year comment on the width of the 20s? Thank you!
